Biology and Environmental Science

In a recent study conducted by the NOAA, the aerosol light absorption coefficient was measured (in Mm-1) at randomly selected locations in Africa and in South America. The resulting data are summarized in the following table.

Country	Sample size	Sample variance
Africa	10	243.36
South America	21	51.84

Is there any evidence that the population variance in aerosol light absorption coefficient is greater in Africa than in South America? Use a = 0.05 and assume normality.
